I get a lot of emails that say "Hey, player X played way more power forward than center". And my response is pretty much always, "yeah, I know but who do you trust?". What it boils down to is my positional data is not very accurate. This is because I do most of this sorta-kinda manually. I mean, basically, once a year I look at Yahoo, ESPN, and some others, and adjust positions but after that I do not monitor them on a game-by-game basis. I watch a lot of basketball but I cannot keep up with that.

There are plenty of solutions for that but they all cost more than I am currently willing to pay. So, instead, I'm going to crowd-source it to you guys!

On most pages where there are player stats, you should see stuff like this:

If you click on that (sorry, it won't work on this page, you'll have to try it out here), you should see a list of other possible positions, and suddenly you get to see what that player's wins produced (or points over par) stats were if all of their minutes were at that position. For instance, we see that if we compare Tim Duncan and Kevin Garnett, Garnett appears to have had a better 2012:

Until you realize that you should probably treat Garnett as a Center:

Head on over to the comparison engine and try it out and let me know what you think.
